Anan Shtaya, John Millar, Owen Sparrow
PURPOSE: The purpose of this paper is to study the presentation and analyse the results of multimodality treatment of brain arterio-venous malformations (AVMs) in children at our centre and review age at first AVM rupture in the literature. METHODS: Of 52 patients aged <18 years, 47 with brain AVMs (27 males and 20 females) aged 4-17 years (mean 12.2) were retrospectively reviewed. PubMed search revealed five additional studies including 267 patients where the prevalence of age-related AVMs rupture was analysed...

BACKGROUND: Randomized controlled trials evaluate the effectiveness of interventions for central venous access devices, however, high complication rates remain. Scoping reviews map the available evidence and demonstrate evidence deficiencies to focus ongoing research priorities. METHOD: A scoping review (January 2006-December 2015) of randomized controlled trials evaluating the effectiveness of interventions to improve central venous access device outcomes; including peripherally inserted central catheters, non-tunneled, tunneled and totally implanted venous access catheters...

PURPOSE OF REVIEW: Central venous catheters (CVCs) have a prominent role in the diagnostic and therapy of neonates and children. Herein, we describe the multiple indications for CVC use and the different devices available for central venous access. Given the prevalent use of CVCs, healthcare systems are focused on reducing complications from their use, particularly central line-associated bloodstream infections (CLABSIs). The most up-to-date information available sheds light on best practices and future areas of investigation...

BACKGROUND: Apheresis treatments can be performed with peripheral venous catheters (PVC), although central venous catheters (CVC) are inserted when PVCs fail or patient with history of difficult vascular access prior to the apheresis. Ultrasound guidance for PVC has shown promising results in other settings. PURPOSE: To investigate if ultrasound guidance for PVC could be implemented among apheresis nurses. Second, how implementation of ultrasound guidance affected the number of CVCs used for apheresis per patient...

High inspired oxygen concentration (FiO2 > 0.85) is administered to test pulmonary vascular reactivity in children with pulmonary hypertension (PH). It is difficult to measure oxygen consumption (VO2) if the subject is breathing a hyperoxic gas mixture so the assumption is made that baseline VO2 does not change. We hypothesized that hyperoxia changes VO2. We sought to compare the VO2 measured by a thermodilution catheter in room air and hyperoxia. A retrospective review of the hemodynamic data obtained in children with PH who underwent cardiac catheterization was conducted between 2009 and 2014...

Thromboembolic diseases such as myocardial infarction, stroke, transient ischemic attacks and pulmonary embolism are major causes of morbidity and mortality worldwide. GPIIb/IIIa is the key receptor involved in platelet aggregation and is a validated target for therapeutic approaches and diagnostic imaging. The aim of this study was to develop and characterize a specific small molecule tracer for positron emission tomography (PET) imaging that binds with high affinity to GPIIb/IIIa receptors and has suitable pharmacokinetic properties to overcome limitations of previous approaches...

AIM: To produce a radiological grading of gastric traumatic injuries. METHODS: In our study, we retrospectively analyzed 32 cases of blunt gastric traumatic injuries and compared computed tomography (CT) data with patients' surgical or medical development. In all cases, a basal phase was acquired, and an intravenous contrast material was administered via an antecubital venous catheter with acquisition in the venous phase (70-90 s). In addition, a further set of delayed scans was performed 4-5 min after the first scanning session, without supplementary intravenous contrast material, to identify or better define areas of active bleeding...

While central venous stenosis is a common consequence of protracted central venous catheter use, intracardiac device transvenous leads, and central venous instrumentation, the majority of patients who develop symptomatic central venous stenosis present with characteristic venous hypertension. However, some patients may develop an abnormal intracranial venous circulation and present with neurologic symptoms. This paper will summarize findings from case reports that describe the neurologic sequelae that can develop as a result of central venous stenosis/occlusion in end-stage renal disease patients with a functional arteriovenous access...

ABSTRACTHemodialysis (HD) and peritoneal dialysis (PD) represent two complementary modalities of renal replacement therapy (RRT) for end-stage renal disease patients. Conversion between the two modalities is frequent and more likely to happen from PD to HD. Every year, 10% of PD patients convert to HD, suggesting the need for recommendations on how to proceed with the creation of a vascular access in these patients. Criteria for selecting patients who would likely fail PD, and therefore take advantage of a backup access, are undefined...

Many guidelines recommend that end-stage renal disease (ESRD) patients should have a permanent vascular access, preferably an autologous arteriovenous fistula (AVF), at the start of renal replacement therapy. Nevertheless, a large proportion of patients still start hemodialysis with a central venous catheter (CVC). On the other hand, there are increasing numbers of patients in whom an AVF has been created, but who never actually end up on dialysis, as well as a substantial number of patients in whom creation of a vascular access has been attempted unsuccessfully...

Arteriovenous fistulas (AVF) improve survival and morbidity for most haemodialysis (HD) patients. Are they better for all patients? In the enthusiastic pursuit of AVFs for all, concerns have been raised regarding high primary AVF failure rates, continued high incident central venous catheter (CVC) use in some countries, and the limited life expectancy of some HD patients. "Fistula first" is changing to "catheter last". The focus must be on decreasing AVF failure to mature and decreasing incident CVC use. An optimal outcome should be sought for each individual patient, and multiple failed attempts at AVF creation avoided...

The ATP monitoring assay is a useful biomarker for risk monitoring to detect infection and rejection episodes in transplant recipients. Hemodialysis patients have a higher rate of infectious mortality. Infections in hemodialysis patients are mainly caused by venous catheters, uremia, malnutrition and inflammation. However, the risk of infection episodes has not been evaluated using a lymphocyte ATP monitoring assay in hemodialysis and chronic kidney disease (CKD) patients. We measured the ATP amounts in the peripheral CD4+ cells of CKD (N = 85) and dialysis patients (N = 17) using an "Immuknow" assay kit...

INTRODUCTION: Most of the patients with iliofemoral thrombosis treated with anticoagulants only are affected with postthrombotic syndrome (PTS) that worsens the patients' quality of life. In the acute phase of proximal deep venous thrombosis (DVT) catheter-directed (CDT) and pharmacomechanical thrombolysis may be a reasonable alternative therapeutic method. Our aim was to summarize our results using these methods. METHODS: Since 2009 twenty-four patients with iliofemoral DVT were treated with these endovascular procedures and with stenting at our Institution...

Autologous breast reconstruction using the deep inferior epigastric artery perforator (DIEP) flap has become increasingly popular because of its unique advantages. However, compared with some other forms of abdominal-based autologous reconstruction, DIEP flaps are associated with an increased risk of venous congestion. Many techniques-or lifeboats-have been introduced to diagnose and treat this potentially devastating complication. In this case report, we describe a novel strategy to augment venous drainage when venous congestion is encountered...

PURPOSE: The aim of this study was to compare the success rate and safety of short-axis versus long-axis approaches to ultrasound-guided subclavian vein cannulation. METHODS: A total of 190 patients requiring central venous cannulation following cardiac surgery were randomized to either short-axis or long-axis ultrasound-guided cannulation of the subclavian vein. Each cannulation was performed by anesthesiologists with at least 3 years' experience of ultrasound-guided central vein cannulation (>150 procedures/year, 50% short-axis and 50% long-axis)...

OBJECTIVE: Central venous occlusion is a common occurrence in patients with end stage renal disease. Placement of upper extremity arteriovenous access in patients with occlusion of the brachiocephalic veins is often not an option. Avoidance of lower extremity vascular access can decrease morbidity and infection. TECHNIQUE: The central venous lesions were crossed centrally via femoral access. The wire was retrieved in the neck extravascular. A HeRo catheter was then placed in the right atrium and completed with an arterial anastomosis...

OBJECTIVE: Acute hyperglycemia causes endothelial dysfunction in diabetic patients, abolishes ischemic pre- and postconditioning, and is an independent predictor of adverse outcome after myocardial infarction in nondiabetic patients. Its effects on endothelial-dependent vasodilation are controversial in healthy subjects. The authors studied the effect of moderate short-term local hyperglycemia on forearm endothelium-dependent vasodilation in healthy volunteers. DESIGN: Randomized, crossover, blinded, 2-visit, pilot design...
